I've suddenly started getting a ERR TXG on 10m & 6m on my 10w K3 (SN 5143). Trying to perform the 5W TX calibration fails when if gets to 10m. Ideas? Thanks, and 73, Ross N4RP -- FCC Section 97.313(a) “At all times, an amateur station must use the minimum transmitter power necessary to carry out the desired communications.”
